There's just two episodes to go in this second season of ABC's "Nashville," and tonight, the gang heads up to Fort Campbell. Tonight's episode will also include an appearance by First Lady Michelle Obama - a cameo that's garnered a very mixed response from "Nashville" fans. Another planned guest spot from Kellie Pickler? Slightly less controversial.

Here's the official word:

"Rayna hosts a charity concert at a military base after she learns Luke was injured in Afghanistan. Meanwhile, Deacon and Maddie grow closer; Teddy thinks he's losing his family; and Jeff upsets Juliette by threatening to tell Avery the truth."

9:14 - One of those weird moments on a TV show where you realize that two main characters have never shared screen time together before (see Jesse and Skylar on "Breaking Bad"). Turns out Gunnar and Juliette hadn't met until tonight. Also hard to believe that "Nashville" has any possible couple combinations left to explore.

9:19 - "I did a couple shows with Merle back in the day." Just when you thought Deacon couldn't get any cooler.

9:22 - "Nashville" has made it to Fort Campbell, Kentucky - just 58 minutes north of Music City. The military base has had quite a few real-deal music stars visit over the years, including Kelly Clarkson and Carrie Underwood.

9:34 - Gunnar and Avery, bro-ing it up on the couch! How far these two have come from smacking each other around in the parking lot of 12th & Porter. Zoey breaks up "guy time" to share the news that she's Juliette's new background singer, and Gunnar opts not to spill the beans on Juliette+Jeff.

9:36 - Scarlett's back waiting tables at the Bluebird, which is a shame, according to one patron who wasn't asked for his opinion.

9:37 - Luke and Rayna have decided they're "all in" with their relationship. We hear Luke and Deacon may or may not come to blows by season finale time.
